Resumen

For determining 22 volatile organic compounds in the atmospheric air, the operating modes of the gas chromatographic complexes «chromatography-mass spectrometer — two-stage thermodesorber» and «gas chromatograph with 2 FID — static headspace analysis sampler» are optimized. The modes provide the values of the separation coefficients of the chromatographic peaks in the range of 1.5 ÷ 21. It has been experimentally established that the highest desorption efficiency of volatile organic compounds is registered when the sample is concentrated into Tenax TA sorption tubes.

Resumen

The parameters for the development of a chromatographic (HPLC) method and its validation are discused in the paper. Chromatographic analysis involves a multi-step procedure consisting of sample collection, pretreatment instrumental measurements and data processing. Emphasize was placed on the instrumental part of the analysis presuming that the contributions of the other variables were minor. The roles of precision, accuracy, detection limit, quantification limit, specificity, selectivity, range, linearity and robustness, as well as system suitability in the analytical application of chromatog

The aim of the present work was to widen the application of an in-house developed fast, flexible and sensitive high performance liquid chromatography (HPLC) method to the assessment of cefotaxime sodium from aqueous samples. The method was applied to establish the release profile of cefotaxime sodium immobilised in MCM-41 nanoparticles using pH controlled release in aqueous medium. The analytical method proved to be sensible, repeatable (RSD < 1.5 %) and reproducible (RSD < 1 %) in the concentration range studied (0.01-10 ?g?mL-1), limit of detection and limit of quantification were 0.03
